To (ZZZ whom it may concern:

Be it known that I, HENRY A. GWEN. d ltates citizen. residing in lVhitins chusetts, haveinvented the fol- *rihed Improvements in Loom ens.

nion is an improvement in side cler motions for automatic looms 'n in United States Letters Pat- $358.72? lvlarch 12, 1918, and No.

I ,oZ. September 10. 1918, and concerns more especially the construction and relative arrangenic t of the trip members in 'nolion or in any side slipping t'eeler or means of which the feeler arm or la '1 structure engages and trips or ope. P 1 call'-transmitting element which hringgs ahout the change in the loom or its stop The accon'ipan ring drawing, illus- 26 51' 1 preferred embodiment of the inventi the method of applying the same to use. is a side elevation of the appaa top plan;

lhe ti-eler motion is carried by a bracket plate 1 supported on the breast-beam or an extension The t'eeler arm or hell crank structure 2 which carries the side slipping i'celer tip 3 is tulcrumed at 4- on a forwardly yielding; fecler carrier 5 and. is itself held fieldingly in a normal or non-calling posh tion on said lcrcr by a light adjustable spring 6 which draws it against. the end of a small set-screw 7 constituting an adjustable stop thcrclor. The spring- (S and the set rcw T are both carried hy the carrier 5 and the latter is pivoted at 8 to the bracket plate 1 and urged reamrardly oi" the loom and against an abutment slop 5) by means ol." a spring 10. )n cwry other heat-up ot' the lay the holihit; or other .ve't't carrier in the shuttle ens iue lcclcr tip and through the latter 2.- .(ilJllU-"l ions. pr:,::-scs the leaner car ier r ll; ll the condition ol' the wound welt on the liohhini not closely up r exhaus ion. the tech-r lip and arm le under this pressure uillund: turnc pivot i; that is to say. it will pintnon-calling position as dicatrd )ljlll held thereto lngaggjlj:

a wed from the front of the loom;

ment of the tip with the Weft, but if the weft is depleted. to a predetermined extent, the tip 3 will slip thereon or therewith, and the feele' arm will then recede in a turned position, such as indicated in Fig. 4:. The turning movement will be observed to arise from the nonalinement of the direction of thrust on the tip with the pivotal support (l) of the feeler arm on its carrier (5) and it is utilized to shift the fecler trip 11 into position to strike, as it recedes, a corresponding abutment 12 on one of the call transmit ting elements such as the lever transmitter 13. and thereby transmit the call to the changing" or controlling mechanism. The trip ll on the feeler arm is formed as a separate pa rt of hardened steel with a round stem mljustahly set-screwed in a socket in th arm and the abutment 12 which is sin ilarlgg formed of hardened steel and setscrewed in the transmitter 13.

The mechanism as thus far described is similar to that or" the aforesaid Patent No. 1,258,727, March 12. 1918.

The present. improven'ient relates to the particular cmistru'ctioirof the forward tripping end of the 't'eeler arm, and of the abut ment of the transmitter. and to their relation to each other. ..is shown in Figs. 2, and l. the tripping end A. of the 'l eelcr arm extends t'orwardl so that normally (that is when the 'leclcr is at rest) the abutment 12. of the transmitter is in the side slipping path of the tripping cod. This normal condition is illustrated in Fig. 2. 'By reason of this re lation. when the lccler tip slides sidewise alone the hohhin. as illustrated in Fig. 4 the forwardly extending tripping end A. of the 'l'celer arm encounters the abutment 12, of the transmitter which thus acts as a stop to limit the side slipping i'novemcnt ol the lecler arm and tip. Accordingly. there is no need for a special extraneous abutment to limit llle side slip of the t'cclcr arm such as is provided in each of the aforesaid patents No. 1.2 8.727. and No. 1.278.732.

flne l'eclcr arm has a push should-er ll. hack ol' the lrippini, end A, and cxlcndi ;r at an ang. thereto. During the normal positior of rest 'ol the lcelcr arm and of the transmitter. and also during the forward and luick mm'emeot ot' the l'ecler and the lecler carrier whih sullicicnl wclt is in the shuttle to prevent the side slip of the i'ecicr tip. the abutment lfhpis out of register with the push shoulder and out of its back and end A, of the feeler arm is stopped by the abutment 12. the push shoulder B, is brought into pushing position relatively to the abutment as illustrated in Fig. 4. As there shown the push shoulder is positioned'immediately behind the abutment so that on the ensuing forward movement of the feeler and its carrier the push shoulder acts upon the abutment thereby moving the transmitter 13, so as to set into action the weft replenishing train of mechanism.

The abutment 12, as shown, is wedge shaped with a sharp edge facing the angle between the tripping end A, of the feeler arm and the push shoulder B, into which it is adapted to enter and seat on the side slipping feeler arm as shown in Fig. 4. This manner of engagement between the tripping end of the feeler and the abutment not only eliminates the need for a special abutment to limit the slip-turning movement of the feeler, such as shown in the patents above referred to, but also improves the action and reduces wear on the contacting edges. The same effect will be attained regardless of whether the .fceler arm or the transmitter carries the push shoulder and whether the engaging parts have the particular shape illustrated. because one will in any event constitute an abutment surface for the other. It will also be apparent that the particular character of the support for the feeler and the dispositions of the parts permitting it to yield to the bobbin and to slip on the weft, and also the instrumentalities whereby the call is transmitted, are all quite inconsequential to the characteristics of tripping means just described. The said call-transmitting means, in the present case, comprises the transmitter 13 fulcrumed at 14: on the bracket plate 1 and kept in inactive position by a spring 15. The operating end of this lever is provided with a cam surface, see detail Fig. 3, whereby it eo-acts with a corresponding surface on a second lever 16 to swing the latter vertically and thereby cause its extended finger to lift or shift the dog 17 into or out of the path of the weft hammer 18 according to the design of the calling agencies and as will be understood by those skilled in the art.

Claims:

1. A loom having a feeler motion comprising, ,in combination, a feeler carrier movable back and forth on the loom, a sideslipping feeler arm movable on the carrier and having its tripping end extending forwardly and a push shoulder atan angle to said tripping end, and a transmitter having an abutment normally standing in the side slipping path of the tripping end of the feeler arm and serving to limit the extent of the side slip, said abutment being normally out of the path of the back and forth movement of the push shoulder, said push shoulder being brought into pushing posi tign relatively to said abutment by the sideshp movement of the feeler arm.

, 2. A loom having a feeler motion comprising, in combination, a feeler carrier movable back and forth on the loom, a side-slipping feeler arm movable on the carrier and having its tripping end extending forwardly, a

transmitter having an abutment normally occupying a position to hunt-the extent of the side slip of the feeler arm, and one of.

said parts (the feeler arm or the abutment) having a push shoulder Which is normally idle but which is brought into active position when the fee-ler arm slips to effect engagement between the feeler arm and the abutment as the teeler carrier moves forward.

In testimony whereof, I have signed this specification.
